Answer: Mike is correct.

Step-by-step explanation:

(2^3) = 8 and 8^5 = 32768

therefore (2^3)^5 = 32768

2^15 is also 32768 while 2^8 is 256.

32768 is NOT equal to 256. Therefore Mike is correct.

lewis rolls a number cube and then chooses a card from a set of cards numbered 1 through 5. What is the probability that he will

iragen [17]

Answer:

$\frac{1}{5}$

Step-by-step explanation:

Sample Space for the Cube, A={1,2,3,4,5,6}

n(A)=6

Even Numbers in A={2,4,6}

Sample Space for the Cards, B={1,2,3,4,5}

n(B)=5

Even numbers in the card,B= {2,4}

The two events are INDEPENDENT Events as the outcome of the cube does not affect the card picked, therefore:

P(A and B)=P(A) X P(B)

= $\frac{3}{6} X \frac{2}{5}$

= $\frac{1}{5}$

Examine this system of linear equations. y – x = 2, x + y = 4 Which is a solution of the system of equations? (1, 3) (2, 2) (3,

Blizzard [7]

Answer:

(1, 3)

Step-by-step explanation:

Solve the following system:

{y - x = 2 | (equation 1)

{x + y = 4 | (equation 2)

Add equation 1 to equation 2:

{-x + y = 2 | (equation 1)

{0 x+2 y = 6 | (equation 2)

Divide equation 2 by 2:

{-x + y = 2 | (equation 1)

{0 x+y = 3 | (equation 2)

Subtract equation 2 from equation 1:

{-x+0 y = -1 | (equation 1)

{0 x+y = 3 | (equation 2)

Multiply equation 1 by -1:

{x+0 y = 1 | (equation 1)

{0 x+y = 3 | (equation 2)

Collect results:

Answer: x = 1, y = 3

The following two functions have a common input, year t: R gives the average price, in dollars, of a gallon of regular unleaded

stiks02 [169]

Answer:

a) F(t) = R[P(t)]

b) the output units of the new function = F(t) in dollars per gallon

Step-by-step explanation:

a) There are two function R(t) which shows the average price in dollars of a gallon of regular unleaded gasoline and P(t) which shows the purchasing power of the dollar as measured by consumer prices based on 2010 dollars.

To write the function which gives the rice of gasoline in constant 2010 dollars ;

From the analysis , this is an example of a composition of function as such the relationship =

F(t) = R[P(t)]

b) the output units of the new function = F(t) in dollars per gallon

This shows that the value of F(t) is the dependent variable
